The release of carbon dioxide industry miniature engines has caused many young technicians ‘ interest in the models in which you can use this reliable, silent, environmentally friendly motor. In the “M-K” have already talked about a few simple ship models with such engines. Today we offer you to make simple model airplane motor CO2. By construction, this classic high set scheme, made without the use of scarce balsa wood — mostly pine and light lime. The fuselage of the model are collected from pine spars a cross section of 2X2 mm and cross-beams of the same section. The Assembly is the simplest slipway, made of two sheets of plywood, covered with plastic wrap — so that the workpiece is not glued to the slipway. Build order is as follows: the rack-bars fixed with pins, then cut between the frame crossmember and finally the joints fill with epoxy glue so that between the blanks formed a fillet — a fillet transition. Billet spars are pre-bent over a candle flame. First, it makes sense to applied to the wall side of the fuselage, and then collect from half of spatial farm. Please note that the front spars of the fuselage together reinforced frame — lime plate thickness of 3 mm, it also serves as the basis for the engine mounts. The front part of the fuselage top and bottom (bottom to the rear edge of the wing and top to the front) paste over fake veneer thickness of 1 mm.
What a pleasure to start the thread right under the clouds even a simple crossing of two strips, covered with tissue paper! But in our time it is available only to inhabitants of rural areas… Try to catch a good steady wind at the site, surrounded on all four sides by a fence of high-rise homes! And try to bring a fragile product to the nearest Park in the crush of urban transport it is almost hopeless.
In Latin language the word “cultivation” means “handling”, “cultivation”. If to explain in more detail, is the process of loosening the previously treated soil with simultaneous cutting of the root system of weeds. But cultivation is not only important for weed control. Tillage improves air and water regimes of the soil, which in turn enhances the activity of soil Microorganisms, creates the conditions for a friendly germination of seeds of cultural plants.
“Look through with great interest your section on “Small machines”: many useful find here Amateur gardeners. I decided to share a simple tool that has served me faithfully for years is terebilo for corn cobs”.
Everyone is used to what is required for forming the matrix and punch. In many cases, however, can do without the surround matrix — sufficient and shaped holes in sheet metal or plywood. But without the surround of the punch!..
Since 1980, the “geography” of the USSR Championships in the sport of flying remained the same — start small rockets passed on two “spaceports” (“Tapani” under Tbilisi and “Aranci” near Tashkent). But to VIII of the championship was selected the sports airfield “fakhrabad” Dushanbe ask.
Unremarkable externally, water tower farm “Precepts of Ilyich” Spassky district, Gorky region. One year supplies the sleep of the villagers spring water. However, coming closer, you will not hear the usual noise water pump operation — he’s not here! And although the source is considerably below the level of the top of the container, water, with only a short respite, rise up! It is not a miracle? No, just Gorky handyman, locksmith-Borsi Yiwu L. Ceranova managed to invent and test the original hydraulic installation, in which for lifting water is used… the energy of the source. We offer our readers acquainted with the principle of operation and device.
Immediately note: we offer avtomodelistov model Cordoba race car, neither in design nor the scheme is not a supernova. All solutions are individually well known, even not too experienced athletes. New design approach for decision models in General.
What can you do — we have no way to get the materials, without which, it seems, is impossible to imagine modern models. A thin fiberglass (not to mention the carbon fabric), the specific binder resins, superdigital and more, thereby yielding better results even in school competitions, this has only dreamed of. And to help these materials in the state, not every corporate enterprise, if at all there is a mug. Well, hope that they eventually can be found in stores at all.
Recently outboard motor was held in high esteem by the water-tourists. However, in recent years a large part of the waters became inaccessible for boats with internal combustion engines. Once again had to recall the sail, to once again take up the oars — Many, however, are not satisfied with traditional propulsion with a muscular drive efficiency the same oars is not too high. No wonder at the time, the paddle wheels were literally pushed by a propeller.
